The narcissist is both victimizer and victim. The essence of the narcissistic disorder is a breakdown of internal communication. The narcissist invents and nurtures a False Self intended to elicit attention - positive or negative - from others and thus to fill his innermost void. He is so engrossed in securing Narcissistic Supply from his sources by putting on an energy-sapping show - that he fails to materialize his potential, to have mature, adult relationships, to feel, and, in general, to enjoy life.
To the narcissist, other people are never more than potential Sources of Supply with a useful "shelf life". The narcissist invariably ends up cruelly devaluing and discarding them, like dysfunctional objects. Little wonder that the narcissist - haughty, abrasive, exploitive, manipulative, untruthful - is universally held in contempt, derided, hated, persecuted, and cast out. But we should never forget that he pays a dear price for something which, essentially, is beyond his full control - i.e., for his illness.
Upbringing and Narcissism
There are no authoritative studies to back a genetic predisposition to pathological narcissism - nor the oft-heard claim that it is the outcome of abuse. But anecdotal evidence, case studies, and the investigation of population in outpatient clinics and so on - reveals a correlation between abuse in early childhood and infancy and the emergence of pathological narcissism as a defence mechanism.
There are many forms of abuse. The most well-known and frequently discussed include incest, molestation, beatings, constant berating, terrorizing, abandonment, arbitrary punishment, capricious and unstable parental behaviour and environment, authoritarian, emotionless, rigid and hierarchical home regime and so on.
But more pernicious are the subtle and socially-acceptable forms of abuse - such as doting, smothering, treating the child as an extension of the parent, forcing the child to realize the parents' unfulfilled dreams and unrealized wishes, putting the child on constant display, maintaining unrealistic expectations of him and so on. These modes of abuse permeate the tenuous self-boundaries formed by the child and teach him that he is loved because of what he accomplishes rather than due to who he is.
Every aspect of the personality is pervaded by pathological narcissism. It colours the narcissist's behaviour, cognition, and emotional landscape. This ubiquity renders it virtually untreatable. Additionally, the narcissist develops deep-set resistance to authority figures, such as therapists. His attitude to treatment is conflictual, competitive, and hostile. When he fails to co-opt the therapist into upholding his grandiose self-image, the narcissist devalues and discards both the treatment and the mental health practitioner administering it.
Mood disorders, compulsive rituals, substance abuse, paraphilias, reckless, or anti-social behaviour patterns often accompany pathological narcissism (they are co-morbid). While some of these coexistent problems can be ameliorated through a combination of medication and talk therapy - not so the core defence mechanisms of the narcissist.
